MOUNTD(8) FreeBSD System Manager's Manual MOUNTD(8)
NAMEmountd -- service remote NFS mount requests
SYNOPSISmountd [-2dlnr] [exportsfile]
DESCRIPTIONMountd is the server for NFS mount requests from other client machines.
It listens for service requests at the port indicated in the NFS server
specification; see NetworkFileSystemProtocolSpecification, RFC1094,
Appendix A and NFS:NetworkFileSystemVersion3ProtocolSpecification,
Appendix I.
The following options are available:
-2 Allow the administrator to force clients to use only the version
2 NFS protocol to mount filesystems from this server.
-d Output debugging information.
-l Cause all succeeded mountd requests to be logged.
-n Allow non-root mount requests to be served. This should only be
specified if there are clients such as PC's, that require it. It
will automatically clear the vfs.nfs.nfs_privport sysctl flag,
which controls if the kernel will accept NFS requests from
reserved ports only.
-r Allow mount RPCs requests for regular files to be served.
Although this seems to violate the mount protocol specification,
some diskless workstations do mount requests for their swapfiles
and expect them to be regular files. Since a regular file cannot
be specified in /etc/exports, the entire file system in which the
swapfiles resides will have to be exported with the -alldirs
flag.
exportsfile
Specify an alternate location for the exports file.
When mountd is started, it loads the export host addresses and options
into the kernel using the mount(2) system call. After changing the
exports file, a hangup signal should be sent to the mountd daemon to get
it to reload the export information. After sending the SIGHUP (kill -s
HUP `cat /var/run/mountd.pid`), check the syslog output to see if mountd
logged any parsing errors in the exports file.
If mountd detects that the running kernel does not include NFS support,
it will attempt to load a loadable kernel module containing NFS code,
using kldload(8) by way of vfsload(3). If this fails, or no NFS KLD was
available, mountd exits with an error.
FILES
/etc/exports the list of exported filesystems
/var/run/mountd.pid the pid of the currently running mountd
/var/db/mountdtab the current list of remote mounted filesystems
